Repair an Index After Validation Fails

You can regenerate a data index if the validation step fails. There are three ways to regenerate an index:

  1. Use the RegenerateIndex configuration parameters and restart the server.
  2. Use the DREREGENERATE index action while the server is running.
  3. Use the IDOL Admin interface.

All these methods recreate all the files for a particular data index without reindexing all your content.

NOTE:

You can also use these methods to regenerate an index after you make a field configuration change. However, you cannot use the RegenerateRefIndex or DREREGENERATE RefIndex option to change the configuration for ReferenceType fields.

Regenerate with a Server Restart

The RegenerateIndex configuration parameters allow you to recreate the data indexes.

Regenerate with an Index Action

The DREREGENERATE action allows you to recreate the data indexes while the server is running. Use this method if you need the IDOL Content component to be accessible while you regenerate.

To regenerate the data index immediately, send a DREREGENERATE index action (case sensitive) from your Web browser:

http://ContentHost:indexPort/DREREGENERATE?&Type=type

where:

ContentHost is the IP address or host name of the machine on which the IDOL Content component is installed.
indexPort is the IDOL Content component index port (specified as IndexPort in the [Server] section of the IDOL Content component configuration file).
type

is the type of subindex that you want to regenerate. You can specify multiple indexes in a comma-separated list. The following values are available:

  • BitField

  • Count

  • Match

  • Numeric

  • NumericDate

  • Parametric

  • RefIndex

  • SecIndex

  • Sort

NOTE:

You can also use the DREREGENERATE index action to regenerate the ReferenceMemoryMappedType field index to restore parent-child relationships for documents that were indexed out of order. For more information, refer to the IDOL Server Reference.

For example:

http://12.3.4.56:20001/DREREGENERATE?&Type=Numeric,NumericDate

This index action uses port 20001 to regenerate the NumericType and NumericDateType field indexes of an IDOL Content component that is located on a machine with the IP address 12.3.4.56.

Regenerate with IDOL Admin

You can also regenerate the data index by using the Regenerate function in the Service Control tab in the Console page of the IDOL Admin interface.

To regenerate the data index by using IDOL Admin

  1. In the Service Control tab in the Console page, click Regenerate.

    The Regenerate dialog box opens.

  2. In the Type list, select the type of subindex that you want to regenerate. The following values are available:

  3. In the Priority list, select the priority for the action, which determines how the action is queued.

  4. Click Regenerate.
